Abstract

The utility model relates to a gravity grading stone removing machine, which relates to grain processing material cleaning equipment. The gravity grading stone removing machine comprises a machine frame, an angular regulator, a sieve body, a material inlet and outlet device, an air suction device, a rubber bearing and a vibration motor, wherein the angular regulator, the sieve body, the material inlet and outlet device, the air suction device, the rubber bearing and the vibration motor are arranged on the machine frame. The utility model is characterized in that material passing groove holes are arranged between the front end of an upper layer sieve body of the material inlet end and a sieve body positioning plate at the front end of the machine frame, and the horizontal gap of the material passing groove holes is between 10 and 18mm. The utility model has the advantages that the material passing groove holes are arranged between the front end of the upper layer sieve body and the sieve body positioning plate at the front end of the machine frame, large stones and heavy materials originally remained on the upper layer sieve body of a material inlet can smoothly fall down on the lower layer sieve surface to be cleaned through the material passing groove holes, the stone removing effect is improved, and the gravity grading stone removing machine is favorable for improving the production efficiency and the economic benefit of use enterprises and is widely applicable to powder manufacture enterprises.

Description

The gravity classification stone remover

Technical field

The utility model relates to grain processing material cleaning equipment, especially a kind of gravity classification stone remover.

Background technology

In the powder process industry, the technical performance of the cleaning equipment of material plays crucial effects to the quality of flour product, because of state's yield wheat ubiquity sand content more, do not exceed standard in order to ensure the flour sand content, powder process enterprise uses two roads to remove stone, existing stone remover is by sieve nest, vibrating motor, air intake device, charging and drawing mechanism and angle regulator constitute, it is to utilize the machine material different with the proportion and the floating velocity of sandstone that the stone principle is gone in its classification, when material is assigned to the upper strata compass screen surface from charging aperture uniformly by drawing-in device, vibration by compass screen surface and air-flow are to the effect of material, make material automatic grading, material that unit weight is little and light weight sundries are suspended in above the material flow, become the oversize of upper strata compass screen surface, the material mouth is discharged on the lenient side, and light impurities such as the material shell of upper strata compass screen surface and dust are siphoned away by the wind net; The material that unit weight is big, sandstone, clod etc. then pass upper strata compass screen surface sky and enter lower floor's compass screen surface and screen below materials flow.At lower floor's compass screen surface, the different impurity such as sandstone, clod that make that utilize material proportion and floating velocity equally form the Ji Shi district along the braided steel wire compass screen surface eminence that crawls toward, and discharge from stone outlet hole successively.Good, the capacious material of quality is discharged by the heavy material mouth, thus the effect that reaches classification and remove stone.But existing classification stone remover can't drop to lower floor's compass screen surface because the reasons in structure between sieve nest and frame has big stone of part and heavy material to be concentrated in the upper sieve feed end, for this reason, must often clear up, not only go the stone effect bad, also influence the raising of three rates of user.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of and is convenient to big stone and heavy material falls smoothly, improves and removes a kind of gravity classification stone remover of stone effect.

Technical problem to be solved in the utility model realizes by the following technical solutions,

A kind of gravity classification stone remover, comprise frame, angle regulator on the frame, sieve nest, charging/discharging device, air intake device, rubber shaft bearing and vibrating motor, it is characterized in that between the front end of upper strata sieve nest of feed inlet end and the frame front end sieve nest location-plate punishment in advance slotted eye being set, the horizontal clearance of punishment in advance slotted eye is 10-18mm.

The utility model is the improvement to existing gravity classification stone remover, between front end by the upper strata sieve nest and the frame front end sieve nest location-plate punishment in advance slotted eye is set, can make big stone on the former upper strata sieve nest that is trapped in charging aperture and heavy material fall to lower floor's compass screen surface smoothly by the punishment in advance slotted eye clears up, structural change between the utility model upper strata sieve nest and the frame sieve nest location-plate, improved and gone the stone effect, help improving the production efficiency and the economic benefit of applying unit, be widely used in powder process enterprise.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model partial structurtes enlarged diagrams.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As depicted in figs. 1 and 2, a kind of gravity classification stone remover is by frame 5, angle regulator 1 on the frame 5, last sieve nest 2, feed arrangement 3, air intake device 4, rubber shaft bearing 6, vibrating motor 7 constitute, between the upper strata sieve nest front end edge of charging aperture and the sieve nest location-plate of frame 5 punishment in advance slotted eye 8 is set, the level interval of crossing hopper sky 8 is 10-18mm, be preferably 10-15mm, big stone and heavy material fall to lower floor's compass screen surface from punishment in advance slotted eye 8, the upper strata sieve nest that has solved existing gravity classification stone remover feed inlet end is detained the phenomenon of big stone and heavy material.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims (1)

1. gravity classification stone remover, comprise frame, angle regulator on the frame, sieve nest, charging/discharging device, air intake device, rubber shaft bearing and vibrating motor, it is characterized in that between the front end of upper strata sieve nest of feed inlet end and the frame front end sieve nest location-plate punishment in advance slotted eye being set, the horizontal clearance of punishment in advance slotted eye is 10-18mm.
